摘要 目的:探讨急性下壁心肌梗死患者体表心电图(ECG)改变与梗死相关动脉(IRA)定位的关系。方法:对42例急性下壁心肌梗死患者的体表ECG与冠状动脉造影(CAG)的资料进行回顾性对比分析。结果:急性下壁心肌梗死患者体表ECG的STI、aVL压低、ST段压低aVL>I、ST段抬高>及ST段压低aVL>I+ST段抬高>时提示急性下壁心肌梗死的IRA为右冠状动脉(RCA)闭塞而不是左回旋支(LCX)闭塞(P<0.001);非ST段压低aVL>I和非ST段抬高>时提示急性下壁心肌梗死的IRA为LCX闭塞(P<0.001)。结论:急性下壁心肌梗死时ST抬高>ST及STaVL压低>STI提示IRA为RCA;若导联ST段抬高不超过导联及非STaVL压低>STI,则提示IRA为LCX。
